New Molecular Tools Enable Researchers To Correlate Viruses, Diseases
Karen Young Kreeger | Feb 4, 1996 | 7 min read
Viruses, Diseases Author: Karen Young Kreeger Sidebar: Professional Resources for Viral Disease Researchers In the mid- to late 1980s, numerous correlations were discovered between viruses and various types of cancers. For example, Epstein-Barr virus was associated with nasopharyngeal carcinoma and B-cell lymphoma, hepatitis B virus with liver cancer, and human papillomavirus with cervical cancer. Now, a decade later, basic and clinical scientists are finding out that viruses may also play a r

Courtesy of Gary Churchill  THE GOOD, THE BAD, AND THE FILTERED: At left is a poor quality microarray with problems due to background contamination. At right is a good quality microarray with well defined spots and low background intensity. Data preprocessing methods can normalize and filter data derived from such images, which may make it impossible to detect problems apparent in the raw image data. Since their rise to fame in the mid 1990s, microarrays have been both lauded and critici
